I did a ton of searching and reading when trying to correctly install the wood body blocks on my 26 Roadster pickup. I took these pics to see if anyone can verify these are correct, and for anyone else who needs to know where to place them. I couldn't find any pics like this when I was trying to figure it out. Hope this helps someone else down the road.

You'll need to remove that little block at the firewall bracket. No wood there, just metal to metal body bracket to frame bracket. Wood there will lift the front of the body up. The front small body bracket is in line with the wood surface of the larger blocks (C) that fill the sub frame channel.

There is small wood pieces (B) up inside the very front body in the sub frame. That wood is just there to place wood screw through the front top of the splash shield for anti-rattle.

You have those "B" blocks, yours are setting on the frame brackets along side the running board braces. Just noted that the blocks are placed in the sub frame channels first, fitted there, then when you lower the body on the frame, the blocks are in place.
